Since your discount is calculated from the total purchase, you do not need to ask for it.
Discount calculations are done using conditional if statements.

Do not use % as a variable name!

All calculations are simple, no need for "from math import *"

You are almost there, please try to understand the logic here ...

def calc_discount(cost):
    if cost > 1000.00:
        discount = cost * 0.1    # 10%
        return discount
    elif cost > 500.00:
        discount = cost * 0.05   # 5%
        return discount
    else:
        # no discount
        return 0.0

Once you know the cost of the purchase then discount = calc_discount(cost) and your final cost will be cost - discount. Not really rocket science, but very simple algebra!
